Directional RNA deep sequencing sheds new light on the transcriptional response of Anabaena sp strain PCC 7120 to combined-nitrogen deprivation [PDF]

open access: yes, 2011
Background: Cyanobacteria are potential sources of renewable chemicals and biofuels and serve as model organisms for bacterial photosynthesis, nitrogen fixation, and responses to environmental changes. Anabaena (Nostoc) sp.

How many metals does it take to fix N2? A mechanistic overview of biological nitrogen fixation [PDF]

open access: yes, 2006
During the process of biological nitrogen fixation, the enzyme nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Nitrogenase consists of two component metalloproteins, the iron (Fe) protein and the molybdenum-iron (MoFe) protein;

Introgression of a Danbaekkong high-protein allele across different genetic backgrounds in soybean

open access: yesFrontiers in Plant Science, 2023
Soybean meal is a major component of livestock feed due to its high content and quality of protein. Understanding the genetic control of protein is essential to develop new cultivars with improved meal protein.

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]

open access: yes, 2014
Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

Sustainable synthesis of amino acids by catalytic fixation of molecular dinitrogen and carbon dioxide [PDF]

open access: yes, 2018
The industrial process of nitrogen fixation is complex and results in a huge economic and environmental impact. It requires a catalyst and high temperature and pressure to induce the rupture of the strong N–N bond and subsequent hydrogenation.

An engineered, non-diazotrophic cyanobacterium and its application in bioelectrochemical nitrogen fixation

open access: yesCell Reports Physical Science, 2021
Summary: The reduction of chemically inert nitrogen to ammonia is a critical step in the global nitrogen cycle. Microbial nitrogen fixation is a promising way to realize nitrogen reduction and ammonia production at mild conditions.

Evaluation of 10 Edamame Breeding Lines to Determine Yield, Agronomic, and Seed Composition Traits

open access: yesHortScience
Edamame is a vegetable soybean (Glycine max) that is harvested at the R6 growth stage. Although it is relatively new to America, the acreage and market demand of edamame have steadily increased.

Nitrogen Fixation in Subtropical Seagrass Sediments: Seasonal Patterns in Activity in Santa Rosa Sound, Florida, USA

open access: yesJournal of Marine Science and Engineering, 2021
Seagrass beds are important coastal habitats that are diminishing globally. Nitrogen, a key nutrient, often limits seagrass growth. Nitrogen fixation provides new, bioavailable nitrogen to the plants.
